Today remove callbacks of platform devices return an int. This is unfortunate because the device core ignores the return value and so the platform code only emits a warning (and still removes the device). The longterm quest is to make these remove callbacks return void instead. This series is a preparation for that, with the goal to make the remove callbacks obviously always return 0. This way when the prototype of these functions is changed to return void, the change is straight forward and easy to review.

interconnect: sm8450: Ignore return value of icc_provider_del() in .remove()

2022-08-16T13:38:35+00:00

icc_provider_del() already emits an error message on failure. In this case letting .remove() return the corresponding error code results in another error message and the device is removed anyhow. (See platform_remove().) So ignore the return value of icc_provider_del() and return 0 unconditionally. This is a preparation for making platform remove callbacks return void.

Merge branch 'icc-rpm' into icc-next

2022-07-15T14:56:31+00:00

This patch set is to support bucket in icc-rpm driver, so it implements the similar mechanism in the icc-rpmh driver. It uses interconnect path tag to indicate the bandwidth voting is for which buckets, and there have three kinds of buckets: AWC, WAKE and SLEEP, finally the wake and sleep bucket values are used to set the corresponding clock (active and sleep clocks). So far, we keep the AWC bucket but doesn't really use it. Link: https://lore.kernel.org/r/20220712015929.2789881-1-leo.yan@linaro.org Signed-off-by: Georgi Djakov

interconnect: qcom: icc-rpm: Set bandwidth and clock for bucket values

2022-07-12T07:04:01+00:00

This commit uses buckets for support bandwidth and clock rates. It introduces a new function qcom_icc_bus_aggregate() to calculate the aggregate average and peak bandwidths for every bucket, and also it calculates the maximum value of aggregated average bandwidth across all buckets. The maximum aggregated average is used to calculate the final bandwidth requests. And we can set the clock rate per bucket, we use SLEEP bucket as default bucket if a platform doesn't enable the interconnect path tags in DT binding; otherwise, we use WAKE bucket to set active clock and use SLEEP bucket for other clocks. So far we don't use AMC bucket. Signed-off-by: Leo Yan Link: https://lore.kernel.org/r/20220712015929.2789881-6-leo.yan@linaro.org Signed-off-by: Georgi Djakov
